Summary of Technical Potential Findings


2. Summary of Technical Potential Findings

This document serves as an addendum to the evaluation results of the Phase II: Program Effects

Evaluation for the PY2010-2012 Emerging Technologies Program (ETP).1 This addendum provides

technical potential findings from an evaluation of the effectiveness of the PY2010-2012 Statewide

Emerging Technologies Program (ETP).

The CPUC commissioned this addendum to provide technical potential for measures adopted into

the IOU EE portfolio in PY2010-2012 from ETP project efforts. The evaluation team was unable to

provide this information in Volume I of the Phase II evaluation report because the ETP database

does not consistently track measures adopted into the IOU EE portfolio. As a result, for this effort,

we requested data for projects adopted into the IOU EE portfolio from the IOUs, and calculated

technical potential for these efforts. Due to enhanced data tracking by the IOUs, this is the first

time that an evaluation team has been able to calculate technical potential and adoption of ETP

projects into the IOU EE portfolio. Tracking of technical potential data is now standard for the IOUs

going forward.

2.1 Technical Potential Program Performance Metrics

On December 2, 2010, the Commission issued Resolution E-4385, approving program

performance metrics2 for the four IOUs for PY2010-2012 statewide energy efficiency programs.

Outlined below are the PPMs related to measure adoption and technical potential in the table

below (see Phase II report for full list of PPMs).

39-40).



Program Element Description PIP Objective^

Centers (TTC) assessments sub-program that are adopted* into the EE portfolio

(and/or available in the market).

* "Adoption” means measure is available to end-use customers through IOU programs. Adoption of a

measure may be attributed to one or more ET sub-programs.

** Potential energy impacts to be reported based on ET project findings and estimated market potential

(reported through quarterly ET database updates) via statistical overview of the ETP portfolio, including

technical potential of measures recommended to the EE portfolio.

***Note that the evaluation effort did not assess TDS program performance metrics.

^There are no adoption objectives for SFP or the overall portfolio.

2.2 Calculation of Technical Potential

Technical potential refers to the energy savings potential that would be captured if all energy

efficiency measures were installed in all applicable and feasible applications, and this is a known

overestimation of total impacts. ETP provides technical potential impacts, not market potential (as

reported in the IOU portfolio impacts). If market potential were included, the savings would be an

overestimate of actual impacts as full market potential is rarely realized. Technical potential are

calculated as shown in Equation 1.

Equation 1. Technical Potential Algorithm

The evaluation team leveraged information collected by the IOUs in the ETP database to calculate

technical potential. The variables used from the ETP database are as follows:

Table 4. ETP Database Variables Used to Calculate Technical Potential

Variable Name Variable Description & Use

Site type or other unit of

measurement (UoM)

Provides the general type of site (e.g., office, single family dwelling) if the unit of

measurement is a single building or the unit of measurements if not a single

building (i.e., square foot of building).

N Sites or units in your

service territory (A)

Estimate based on assessment - this value is the total of whatever unit provided

as UoM (variable above) within your service territory (e.g., 3,000,000 SFD or

1,200,000 MFD or 1,800 office buildings or 2.8 billion square feet of

commercial space).

Percent of population in

your service territory who

could use this technology

(B)

Estimate based on assessment - this is the percent who could use the

technology, regardless of the cost effectiveness or if they wanted to do so. This

is not always 100%.

Annual kWh / site or unit

(C)

Estimate based on assessment - this is the kWh savings for a single unit of

measurement (technical potential = A*B*C)

Peak kW Savings / site or

unit (D)

Estimate based on assessment - this is the kW savings for a single unit of

measurement (technical potential = A *B * D)

Annual Therm Savings / site

or unit (E)

Estimate based on assessment - this is the gas savings for a single unit of

measurement (technical potential = A * B * E)



2.3 Adoption and Technical Potential Findings

In PY2010-2012, the IOUs were required to report on all ETP PPMs at the end of the three-year

portfolio cycle. For the next program cycle, the IOUs will track PPM’s annually and will be able to

leverage their enhanced data tracking to support their reporting efforts.

Overall, we found that 131 measures, resulting from or influenced by 53 ETP projects, were

adopted into the IOU EE portfolio in PY2010-2012.

Statewide 53 131

Source: ETP database provided in October 2013. (a) Represents unique measures, i.e. the same measure from two or more projects is counted as one

measure. Note that we count custom efforts as one measure.

There are various terms used to describe ETP activities, which are used differently by each utility;

these include “project”, “technology”, and “measure”. We provide one way to differentiate these

terms below:

Project: ETP is project based, there were 53 projects, which resulted in 131 measures

adopted into IOU EE portfolio in the PY2010-2012 program cycle, representing multiple

technologies.

Technology: A technology is an equipment, practice or approach that can cover any end-use.

One technology could be assessed by multiple projects. For example, there were multiple

projects assessing LED technology in this program cycle.

Measure: A measure is an application of a technology that may ultimately have a different

incentive level, potential market sector, etc. For example, the LED technology could

subsequently result in multiple measure codes within the energy efficiency portfolio.

The IOUs report adoption using different units. PG&E reported values as projects, whereas the other

IOUs reported as measures. The ETP database3 tracks program activities by unique ETP project

identifier (which may or may not equate to the PG&E project definition). The PPMs represent

measures adopted into the portfolio. Below we include the adopted project or measure values as

shown in the June 3, 2013 IOU report compared to values from the ETP database provided by the

IOUs. Notably, there is a difference between the IOU reported values and the recent data request.

3 The ETP database was created to provide greater insight into ETP program activities by activity. For more information on

the ETP database, please refer to the Phase I PY2010-2012 report; Volume II.

Table 7 provides projects that resulted in measures adopted into the IOU EE portfolio in PY2010-

2012by program element. We found 25 instances where two different projects could result in the

same measure. This is consistent with ETP element design, where a Technology Assessment

project could be moved into a Scaled Field Placement or Demonstration Showcase project.

An additional ETP PPM states that ETP projects support three specific technology types: advanced

HVAC technologies, high-efficiency plug loads and appliances, and advanced lighting technologies.

Approximately 58% of ETP projects resulting in adopted measures cover these technology types

(Figure 1).

End-Use

Overall, 13 projects had measures adopted into a custom program, 19 projects had measures

adopted into a prescriptive program and 20 projects had measures adopted into both custom and

prescriptive programs, and one project did not have a designated program.4

Figure 2 shows that majority of statewide projects were for the commercial and industrial sectors

(66%). Of the 53 projects that resulted in measures adopted into the IOU EE portfolio, 35 are for the

commercial and industrial sector, 9 are for the residential sector, 5 are for both the commercial

and residential sectors, and 4 are unknown.

*Findings from ETP database variable “Sector”, which provide one response category per project ID.

2.4 Conclusions & Considerations

Below we provide a summary of conclusions and considerations from this effort.

In PY2010-2012, 131 measures, resulting from 53 ETP projects, were adopted into the IOU EE

portfolio. These measures represent a technical potential of 6,288,461 MWh, 1,480 MW, and

217,416,951 therms.

We found that the measures align for the most part with the California Energy Efficiency Strategic

Plan (CEESP) and PPM end-uses, although the program also transferred measures that support

other portfolio needs.

The majority of measures support commercial and residential sectors.

We understand that technical potential does not provide a comprehensive assessment of program

effectiveness. It is a single data point that is a known over-estimation as it does not include market

potential. However, technical potential does provide context to ETP program efforts by providing a potential

scale of eventual contributions to the IOU EE portfolio.

As per the requirements of the California Energy Efficiency Evaluation Protocols (Emerging Technology

chapter), future evaluations should also track ETP measures adopted into the portfolio. This measure

tracking would provide ETP measure uptake and associated ex ante energy savings within the IOU EE

portfolio. When tracked over time, this parameter will provide additional information regarding market

adoption (which technical potential does not incorporate) as well as provide information regarding ETP’s

actual contribution to the EE portfolio. As noted in the Protocols, the goal of this effort “is not to attribute

savings directly to ETP as a resource, but to show a clear trail of which ETP technologies are being

accelerated into utility energy efficiency programs.”5 This language acknowledges that once ETP staff

transfer a measure to the EE portfolio, its uptake in the portfolio is a function of EE program design and

implementation and outside the control of ETP. However, only by tracking this parameter can “an

evaluation adequately answer the future questions posed by key stakeholders regarding the ultimate

impacts of ETP activities”6

3.1 Revisions to Data

To calculate the technical potential accurately, the evaluation team made minor changes to the data received. We document these

changes below:

Removed duplicate measure codes: Consistent with ETP element design, where a Technology Assessment project could be

moved into a Scaled Field Placement or Demonstration Showcase project, multiple project ID’s could correspond to one

measure code with the same savings values. As such, to accurately calculate the technical potential, duplicate project IDs

with the same measure code and savings values were removed. This was done for two PG&E projects:

o ET09PGE0917 due to duplicate measure code with ET10PGE1001

o ET12PGE3301 due to duplicate measure code with ET11PGE2201
